dispose of the excess as directed
You can return the excess amount of the solid chemical back to the reagent bottle if it is safe to do so. If not, you should dispose of the excess chemical properly according to your institution's chemical waste disposal guidelines. It's important to always follow proper safety procedures and guidelines when handling chemicals.

No, the excess reagent does not determine the amount of product formed in a chemical reaction. The amount of product is determined by the limiting reagent, which is the reactant that is completely consumed first. The excess reagent will remain in excess after the reaction is complete.
To determine the amount of excess reagent in a chemical reaction, first calculate theoretical values for your reaction to get an estimation of how much of your excess reagent will be left once the limiting reagent is used. Then run the actual experiment and measure!
In back titration, a known excess of a reagent is added to react with the analyte. After the reaction is complete, the amount of excess reagent is determined by titration with another reagent. The difference between the initial amount of excess reagent and the amount required in the back titration is used to determine the amount of analyte present.

the amount of limiting reagent
To find the limiting reagent in a chemical reaction, you calculate the amount of product that each reactant can produce. The reactant that produces the least amount of product is the limiting reagent. You can then use this information to determine the amount of product that can be formed in the reaction.
To determine the amount of excess reagent in a chemical reaction, first calculate theoretical values for your reaction to get an estimation of how much of your excess reagent will be left once the limiting reagent is used. Then run the actual experiment and measure!
The limiting reagent in a reaction is the reactant that runs out first. For example, if you are reacting 10 moles of HCl and 5 moles of NaOH, you will get 5 moles of H20, 5 moles of NaCl, and 5 moles of HCl, because the remaining HCl had nothing to react with. Therefore, the NaOH is the limiting reagent.
To determine the limiting reagent in a chemical reaction, compare the amount of each reactant used to the stoichiometry of the balanced equation. The reactant that produces the least amount of product is the limiting reagent because it is fully consumed first, limiting the amount of product that can be formed.
it may be , the limiting reactant is that which is totally consumed during the reaction but its amount must be less than required amount with respect to excess reactant for example, H2SO4 + 2NaOH = Na2SO4 + 2H2O in this reaction suppose acid is 95 g and base is 85 g but acid with higher amount is the limiting reactant and base is in excess. Essentially, it's possible whenever the molecular weight of the limiting reagent is higher than the molecular weights of the other reagents.
Determining the limiting reagent in a reaction is important because it helps identify which reactant will be completely consumed first and thus limits the amount of product that can be formed. This information is crucial for calculating the maximum amount of product that can be obtained from a reaction and for ensuring that resources are used efficiently.
